The three indicators we lean on — and how to read them without fooling yourself

There are something like a hundred technical indicators floating around, and the internet will happily sell you a course on every one of them. Most are variations on a handful of simple ideas. After a lot of testing, these are the three we keep coming back to — not because they predict the future (none of them do), but because each answers one specific, honest question about the chart.

One thing first: a single indicator is never a signal. RSI flashing oversold means nothing by itself. The value shows up when several independent readings point the same way. That's the whole idea behind how Pairvue scores a setup, and it's how we'd suggest you read these too.

RSI — "has this moved too far, too fast?"

The Relative Strength Index runs from 0 to 100 and tries to measure momentum. Below 30 usually gets called oversold; above 70, overbought.

The mistake people make is treating those two lines as buy and sell buttons. They aren't. In a strong trend, RSI can sit pinned above 70 for days while price keeps grinding higher, and "overbought" puts you short straight into a rally. We read RSI as a question, not an answer: price has stretched — is anything else backing up a turn? If nothing is, the stretch can go a lot further than feels reasonable.

MACD — "is momentum actually shifting?"

MACD watches the gap between two moving averages. When its lines cross, momentum is changing direction. A bullish cross after a long slide is the kind of thing worth a second look.

Its weakness is the flip side of its strength: it lags. By the time the cross is clean and obvious, part of the move has already happened. It also gets noisy in a sideways market, firing crosses both ways that lead nowhere. We use MACD for confirmation, not as the first thing we reach for.

Support and resistance — the one most people underrate

This one isn't a fancy oscillator. It's just the price levels where the market has turned before, again and again. And honestly, if we had to throw the other two out, this is the one we'd keep.

Levels are where decisions actually get made. A buy near support has a clear, nearby place to be wrong — just under the level — which means you can size the trade and define your risk before you click anything. A signal floating in the middle of nowhere, with no level beneath it, is a signal with no plan. Most of the indicators people obsess over are trying to time momentum. Support and resistance tells you where that momentum is likely to matter.

Put them together

None of these three is impressive on its own. RSI says price is stretched. MACD says momentum is turning. Support says there's a level right here to lean on. When all three agree, you've got something worth looking at. When they argue, you've got a good reason to wait.

That's not a magic formula, and we won't pretend it is. It's a way of reading a chart that keeps you honest about what you actually know versus what you're hoping for. When real money is on the line, that gap is most of the game.
